The administrative procedure is the formal way of the acts through which the administrative action takes place to accomplish a purpose. The goal is the issuing of an administrative act.
The obligation to obey strict legal channels ensuring the security of citizens distinguished the public action of the private activity. This warranty is given by the legal order and the security of knowing that the information can be known and subject to tax by all persons.
Thus, the administrative procedure is somehow the guarantor of administrative action, cannot be neither arbitrary nor discretionary because it must abide by the rules of procedure.
The administrative procedure encompasses four key principles, namely: the principle of unity, the principle of contradiction, the principle of impartiality and the principle of officiality.
The principle of unity argues that the procedure is a single process that has a beginning and an end (it should be resolved shortly in any initial form).
According the principle of contradiction, the resolution of the procedure is based on the facts and the foundations of law, subject to verification of the facts and evidence.
The principle of impartiality ensures that the action will take place without favoritism or enmities. Officials must refrain from if they have a personal interest in the case, a relationship or a certain friendship/enmity, or even if they are part of the witnesses.
Finally, the principle of officiality requires that the procedure be developed Office during all steps.
